Property Default Value

Hello,

I have a class with two properties:

public String DefaultCulture { get; set; }
public String Cultures { get; set; }

What is the correct way to define a default value for each one if they
are not defined?

Thanks,
Miguel
 
In the class constructor, you can set the values to whatever you need. But,
since you won't have a property backing field using this syntax, you'll have
to set the default value directly on the property.

You should be more specific. For one, the value of each property _is_
always defined. If you don't initialize it, it's initialized to null
for you.

There is the [DefaultValue] attribute, which you can use to indicate to
the VS Designer what the default value for the property should be. But
that's used only by the Designer; you still need to implement the
default value in your own code.

If you want to have the concept of a property that is as-yet unassigned,
you cannot do that with automatic properties. That's because to track
assignment of the property would require an explicit implementation of
the setter, and to return something other than the currently assigned
value of the property would require an explicit implementation of the
getter.

If the above doesn't answer your question, you should clarify the question.

Default values should be set in the constructor, when you are
using automatic properties.

I would most likely prefer to use:

public CultureInfo DefaultCulture { get; set; }
public CultureInfo Culture { get; set; }
